The new findings are an independent line of evidence that hydrothermal activity is taking place in the subsurface ocean of Enceladus. Earlier results, published in March 2015, indicated hot water is interacting with rock beneath the sea of this distant moon. The new discoveries support that conclusion and add that the rock appears to be reacting chemically to produce the hydrogen.
We earthlings love to look up at the moon. So much does the moon enamor us; we write movies, songs and poems by the droves that contain the name of the earth's super satellite. A case in point is the fact that one of the biggest selling record albums of all time is Pink Floyd's "Dark Side of the Moon."
GRAIL Mission Puts A New Face On The Moon! Scientific investigation into the origin of lunar impact basins has been hampered because there is a general lack of agreement on their size. The majority of the largest impact basins pock-mark the near-side of the Moon (the Moon's enchanting "face"), and have also been filled in by gushing lava streams. These lava streams have covered up, and rendered invisible, important clues pertaining to the shape of the land.
